Cylindrical, vacuum-tight stainless steel distillation boiler Insulated heating jacket; standard version: floor and lower jacket surface with integrated electrical heating elements and filled with thermal oil / with heating elements and filled with water (maintenance-free heating, max. heating temperature 130 °C). Alternatives: Connection to an on-site hot water, steam or thermal oil network Water-cooled stainless steel condenser A rotating scraper system (rotor) prevents deposit build-up on the heating surfaces and agitates the material to be distilled Dirt-resistant discharge valve, operated manually or pneumatically The unit rests on sturdy frame with stairs at the side and an observation platform (accessory for ROTO 9) The discharge height is adapted to the disposal container and/ or a 200-l-barrel (on a pallet) (accessory for ROTO 9, standard discharge height 650 mm). Other heights are possible Optional: adapted residue carriage (only with ROTO 9) A viewing glass and an explosion-proof halogen lamp permit operators to observe the distillation process Automatic filling stop by means of a vibration limit switch and a pneumatic ball valve in the filling line Batch distillation or continuous distillation Explosion-proof control elements at the distillation unit for vacuum, filling, heating, rotor rotation and EMERGENCY STOP Programmable logic controller (PLC) with display for text, input of and/or information on the chronological sequence of the vacuum, filling, heating and rotor functions and the distilling-off times Accessories Vacuum unit for lowering process temperatures, with either a liquid ring vacuum pump (for solvents with a flash point > 55 °C) or a liquid jet vacuum pump Residue temperature control system for processing heat-sensitive substances Distillation output monitor for automatic distillation stop when the output drops below a set limit Timer for automatic distillation start Seal plate or exhaust hood adapted to on-site disposal container, optionally with an air extraction system Thermostatic valves if the unit is connected to an on-site cooling/ public water supply; separate cooling water devices with separate circuits are available as option Distillation unit Output depends on the solvent If water from a public system is used; depends on the water temperature and the boiling point of the solvent; a closed cooling circuit with zero water consumption is possible
